Cancun Krystal Hotel is located in the Hotel Zone at Km 9.5 Marker. From the Hotel Tower "A" rooftop looking southeast along the seaward side beach. Great peaceful view of the hotel zone and the peaceful Caribbean Sea shore line.
While my facial expression might suggest an odd grimace, it really is caused by the overly bright tropical sun light. And I was struggling to hold vertical the four foot monopod atop a 3 foot high wall.
The hotel is 1 block from the Convention Center. In the background you can almost see the top of renovated Hyatt now the Krystal Grand Hotel (Plan: all inclusive).
Observation: Seems the hotel ownership change names and ownership every two or three years. But the hotel locations remain the same. We have been visiting this hotel for last 15 years. Great peaceful hotel in September because Spring break (March and April) folks are back in school or at home.
